The present invention relates to a rail anchor for anchoring railsagainst creeping. In case where most of the traliic on a railroad is inone direction or where the heavy traffic is in one direction with theempty cars returning in the opposite direction the rails have a tendencyto creep along the ties. Various devices have been employed to corrector arrest this creeping of the rails but most of these devices areeither so complicated as to be expensive and difficult to install orelse have a tendency to loosen and thus destroy their usefulness.

An object of the present invention is to 5 make a strong, simple, andeffective rail anchor which may easily be installed and which willrequire a minimum of up-keep and repairs.

In order to attain this object there is pro- 2 vided, in accordance withone feature of the invention, a pair of jaw members adapted to engagethe sides of the base portion of a rail, one of said members beingadapted to lockingly engage the head of said bolt. These members arepositioned to engage a side of a railroad tie to anchor the rail againstcreeping. These and other features of the invention will be more fullybrought out in the following description and the accompanying 3odrawings wherein:

Figure 1, is a View in top plan of a portion of a. rail mounted upon aportion of a tie with the anchor device in position on the base of therail.

Figure 2, is a vertical sectional view of the device shown in Figure 1showing the rail in section and the tie and anchoring member inelevation.

Figure 3, is avertical sectional View through the anchoring member andthe base of the rail.

Figure 1, is a view in perspective of one of the jaw members that engagethe base of the rail.

Figure 5, is a view also in perspective, of the other aw member.

Figure 6, is a sectional view on the line 6-6 of Figure 3.

Referring to the drawings in detail, the anchor comprises a jaw member 1having a ce s hereinto ngage the base flang 3 f a railway rail i- Th s'jaw em r pm:

to the jaw member The u seat h head of the bolttfi is provided with fourgrooves 12 one adjacent to each edge of the head of the bolt 6 toregister with the lockingpin groove 10 of the anchor member .7 for eachdegrees rotation of the bolt 6.

In using the device a jaw member 7 is slipped over the shank of the bolt6 and the bolt is threaded into the opening 5 in the jaw member 1. Thejaws are separated to a distance greater than the width of thebaseflange of the rail and are then slipped beneath the base-flange ofthe rail and the device is moved closely adjacent a side of the tietoward the direction from which the heaviest traflic comes. The bolt 6is then turned by a means of a suitable wrench to draw the jaws 1 and 7together, firmly gripping the base-flange of the rail 4 between them.

When drawn to the point of maximum pressure the bolt head is turned sothat one of the grooves 12 in the bolt-head is in register with thelocking-pingroove 10 in the jaw member 7. A locking-pin which ispreferably of a size to have a close driving fit in the opening providedby the grooves 10 and 12 is then driven into this opening to firmly lockthe bolt 6 against rotation relative to the jaw member 7 and the railbase. The other jaw member 1 is of course held against rotation by itsengagement with the base-flange of the rail so that no displacement ofany of the parts is possible without distorting some of the members orremoving the locking-pin 11.

The device is simple and effective in operation, easy to install and asit comprises but four operative parts including the lockingpin the costof the device is extremely low. The device may be shipped completelyassembled except for the locking-pin so that there are no loose nuts orparts to be lost.

I claim:

A rail anchor, comprising a bolt having a groove on the inner face ofthe head thereof, a jaw member having a rail gripping groove at the topon the inner side thereof and having a portion thereof extending belowthe bolt when in an operative position to engage a tie, and having asmaller groove in the outer face thereof to coincide with the groove inthe bolt head; a second jaw member having a groove therein to lie abovethe bolt on the inner side of said jaw member when said jaw member is inan operative position and having an extension beneath the bolt when thejaw member is in an operative'position to engage a tie, and having athreaded opening therein to threadedly receive the bolt to draw the jawmembers together to grip a rail flange ,therebetween, and a pinadaptedto be inserted in the opening formed by the coinciding grooves onthe inner side of the head in the outer side of the first jaw members toprevent rotation of the bolt with respect to the jaw members.

p In testimony whereof I affix my signature.
